RING aims to combine the returns from 30+ DeFi protocols carefully selected by our team and redistribute the yield to you. Hence, your risk is minimized and the fees are erased.

RING.swapAndSendToFee(address,uint256) (#2470-2476) sends eth to arbitrary user
Dangerous calls:
- address(destination).transfer(newBalance) (#2475)
RING.addLiquidity(uint256,uint256) (#2509-2522) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,address(0),block.timestamp) (#2514-2521)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
